Leveling in Ninja.io can be split into 2 categories: skill levels and experience levels.

Skill Levels

Skill is roughly calculated as follows:

skill = kd_ratio * quality * activity

kd_ratio is kill/death ratio.

quality is determined by average experience obtained from kills. Higher quality indicates more sprees and more kills of players with good ratios themselves.

activity is based on activity over the past 10 days. Having less than 2000 kills over the past 10 days will result in a lower activity value.

A high skill value can be obtained by killing at least 2000 players every 10 days, by making sure that you kill good players and make lots of combos, and by keeping your k/d ratio high.

The following skill titles can be obtained:

Min Max Title
0 1200 Newbie
1200 2700 Beginner
2700 4500 Novice
4500 6600 Initiated
6600 9000 Trained
9000 11700 Competent
11700 14700 Adept
14700 18000 Skilled
18000 21600 Proficient
21600 25500 Advanced
25500 29700 Expert
29700 34200 Elite
34200 39000 Champion
39000 44100 Master
44100 49500 Grandmaster
49500+ Ninja

Note that flag caps and DM / TDM / CTF / DB wins have no bearing on skill level. These will be displayed & ranked separately in a future update.

Experience Ranking

Players level according to a point system.

Killing a person who is performing roughly equal will yield 100 points. Killing an inactive guest or a guest with no kills will yield no more than 1 point. A kill can yield no more than 200 points, however sprees (double kills and triple kills) multiply the amount of points.

The maximum attainable level is be 160. It requires on average 64.000 kills of equally performing players to reach the highest level.

Every 16 levels, you get a new shuriken (note that these are not the same shurikens that you use to fight ingame):
